NEUer at SemEval-2021 Task 4: Complete Summary Representation by Filling Answers into Question for Matching Reading Comprehension
Zhixiang Chen, Yikun Lei, Pai Liu +1
SemEval task 4 aims to find a proper option from multiple candidates to resolve the task of machine reading comprehension. Most existing approaches propose to concat question and o…
BiGCN: A Bi-directional Low-Pass Filtering Graph Neural Network
Zhixian Chen, Tengfei Ma, Zhihua Jin +2
Graph convolutional networks (GCNs) have achieved great success on graph-structured data. Many graph convolutional networks can be thought of as low-pass filters for graph signals.…
Faster Deterministic Algorithms for Packing, Matching and -Dominating Set Problems
Shenshi Chen, Zhixiang Chen
In this paper, we devise three deterministic algorithms for solving the -set -packing, -dimensional -matching, and -dominating set problems in time ,…
Approximating Multilinear Monomial Coefficients and Maximum Multilinear Monomials in Multivariate Polynomials
Zhixiang Chen, Bin Fu
This paper is our third step towards developing a theory of testing monomials in multivariate polynomials and concentrates on two problems: (1) How to compute the coefficients of m…
Algorithms for Testing Monomials in Multivariate Polynomials
Zhixiang Chen, Bin Fu, Yang Liu +1
This paper is our second step towards developing a theory of testing monomials in multivariate polynomials. The central question is to ask whether a polynomial represented by an ar…
The Complexity of Testing Monomials in Multivariate Polynomials
Zhixiang Chen, Bin Fu
The work in this paper is to initiate a theory of testing monomials in multivariate polynomials. The central question is to ask whether a polynomial represented by certain economic…
